 so is the whole order of the inorganic Universe. 

 There can, therefore, be no possibility of an animal 

 or plant appearing out of its proper environment.

 but the continuous links of a chain in which the 

 higher types are simply connected with the lower 

 in direct continuity. It is the old scale of Aristotle

J. B. Rene Robinet (i 735-1820) was another of 

 the speculative group. In his two works, — Dc la 

 Nature, published in 1766, and Considerations Phi lo-
